package com.android.wei.zidingyi.adapter;import android.app.Activity;import android.os.Bundle;import android.view.Window;import android.view.WindowManager;import android.widget.Gallery;import android.widget.GridView;import java.util.*;public class MyActivity extends Activity { private Gallery gallery; private GridView gridView; private ImageAdapter listViewAdapter; public static ImageAdapterView imageAdapterView; private List<Map<String,Object>> listItems; private Integer[] imgeIDs = { R.drawable.niao,R.drawable.niao,R.drawable.rui,R.drawable.rui, R.drawable.ning,R.drawable.ning }; private String[] goodsNames={ "土豆丝","土豆块","土豆泥","红烧土豆", "麻辣土豆","清蒸土豆" }; private String[] goodsDetails={ "土豆丝：便宜又好吃","土豆丝：便宜又好吃","土豆丝：便宜又好吃", "土豆丝：便宜又好吃","土豆丝：便宜又好吃","土豆丝：便宜又好吃", }; private int[] money={ 2,3,3,10,8,13 }; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); /**全屏显示**/ requestWindowFeature(Window.FEATURE_NO_TITLE); getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN); setContentView(R.layout.main); gridView=(GridView) this.findViewById(R.id.gridView1); imageAdapterView = new ImageAdapterView(this); gridView.setAdapter(imageAdapterView); gallery = (Gallery) this.findViewById(R.id.gallery1); listItems = getListItems(); listViewAdapter = new ImageAdapter(this,listItems); gallery.setAdapter(listViewAdapter); } private List<Map<String,Object>> getListItems(){ List<Map<String,Object>> listItems = new ArrayList<Map<String,Object>>(); for(int i=0;i<goodsNames.length;i++){ Map<String,Object> map = new HashMap<String,Object>(); map.put("image", imgeIDs[i]); map.put("title", goodsNames[i]); map.put("info", money[i]+"元"); listItems.add(map); } return listItems; }} 然后是Gallery的
